Features of Superiority 


AMERICAN PEERLESS 
WALL RADIATORS 


HE AMERICAN Peerless Wall Radiator is the foremost 

improvement in the heating field, for it replaces the 
troublesome pipe coil and other antiquated types of heat- 
ing surface. As the pipe radiator of years ago was replaced 
by the cast-iron form, so the coil has been supplanted by 
the AMERICAN Peerless Wall Radiator. 


The AMERICAN Peerless Wall Radiator was developed 
to supply a demand for efficiency, and it has been suc- 
cessful. A study of the design will show elimination of 
friction-giving passages, which feature allows operation 
with less power, pressure or vacuum, as the case may be, 
and eliminates many air-venting problems. 


The mechanic approves of this type of radiation, since 
he can always make a proper circulating as well as a good- 


looking job. The owners will like it because it looks better, 
fits in better, is more efficient, and occupies less space. 


The AMERICAN Peerless Wall Radiator does not wear 
out. The story of replacing heating surface after a number 
of years is now obsolete, for AMERICAN Peerless Wall 
Radiators are a part of the building as much as the ground 
upon which it is built. Being made of cast iron, it can 
stand the roughest use in any type of heating plant. The 
sections are connected together by means of heavy right- 
and left-hand nipples of malleable iron, and the connect- 
ing openings are made with cast-iron bushings. Nipples 
are several times the weight of standard pipe (this at the 
thread line). Being made of malleableized iron, these 
nipples exhibit the same remarkable resisting qualities to 
the action of steam and water as does the radiator surface.

Features of Superiority —Continued 


We gladly supply, on request, a series of laboratory test 
sheets showing, under 2 pounds steam pressure at boiler, 
an average coefficient of 2.121 per square foot of AMER- 
ICAN Peerless Wall Radiators. 


The water content of these Radiators is about fifteen- 
hundredths of a gallon per square foot. 


All regular AMERICAN Peerless Wall Radiators are tested at 
factory to 100 to 120 pounds pressure. Radiators for higher 
working pressure than 40 pounds can be made on special 
order. Sections weigh about 7 pounds per square foot. 


Many combinations of groupings can be made and, with 
a little thought, very successful applications are possible. 


AMERICAN Peerless Wall Radiators never lose their value. 
If a building is remodeled, extended or otherwise altered, 


they can always be used again without loss—100 per 
cent salvage! 


Ingenious methods of supporting AMERICAN Peerless Wall 
Radiators are shown—on walls, on ceilings, on girders and 
in almost any part of the building. As illustrated, the in- 
stallation is simple—the Arco Brackets, Supports, 
Hangers, Pendant Flights, Post Supports or Inserts being 
set and the Radiator placed on them and adjusted for 
pitch. These splendid devices, together with the Clearway 
Forms and Backset Connections, constitute an unequaled 
line of accessories, which will do much to advance and 
popularize heating. 


The following pages contain descriptive matter, show- 
ing methods of application, measurements, surface, in- 
Stallations, telegraph code, etc.

Arco and Arco Junior Adjustable Brackets 


RCO Adjustable Wall Brackets have many unusual 

features and fulfill the demands of the most difficult 

installations. They are strong, easy to erect, adjustable, 
and they make a neat and attractive job. 


Expansion and contraction are provided for, no matter 
how long the run of Wall Radiators may be. The spools 
on the bottom Bracket allow a free horizontal movement 
of the Radiators, thus taking care of any difference in 
“‘roughing in’’ measurements, and affording free play for 
expansion and contraction. Unsightly, sagging, air-bound 
runs of pipe coil need no longer be tolerated. 


The V-shaped spool makes it impossible for the Radiator 
to jump from the Bracket. The finger of the top Bracket 
guides the Radiator and keeps it from tipping forward. 


By the use of these Brackets, which permit a vertical 


AMERICAN PEERLESS 
WALL RADIATORS 


adjustment of 2 inches, the fitter can adjust for ‘“‘pitch”’ 
after they have been attached to the wall. The Single- 
Spool Brackets set the outer face of the Radiator 434 
inches from the wall. Retaining bolt is 14 inch diameter. 


Bearing plates and bolts of ARCO and Arco Junior Ad- 
justable Wall Bracket are of wrought iron. The remainder 
of the Bracket is made of malleable iron. 


Arco Junior Wall Bracket 
The Arco Junior Wall Bracket is made for smaller units 
of radiation; it requires only one bolt for fastening, as 
shown; has an upright alignment of 11% inches and a hori- 
zontal slip of 1 inch. 


This type of Bracket can be economically used on all sizes 
of AMERICAN Peerless Wall Radiators where extreme 
expansion is not to be considered.

Good Practice for Installing 


Ahee increasing use of AMERICAN Peerless Wall Radi- 
ators, hung on ARco Adjustable Wall Brackets to 
walls and partitions, prompts us to suggest the following 
simple and practical methods of installation, which insure 
good jobs. 


For attaching ARCo Adjustable Brackets to stone, cement 
or brick walls the proper use of the expansion bolt always 
gives the best results. Ordinary nails and screws frequently 
work loose, pull out or break and cannot be depended 
upon for secure and permanent work. 


Progressive fitters have found that the following method 
saves time and gives best results: 


To start the hole in the wall, use a “‘rose drill.’’ After 
carefully locating the hole centers, start the hole with light 


AMERICAN PEERLESS 
WALL RADIATORS 


blows of the hammer, being careful not to allow the drill 


to jump about. Thus a smooth bore is started without 


cracking the surface of the wall adjacent to the hole. After 
hole has been drilled about 14 inch use more force, being 
careful to turn the drill slightly between 
blows, as this prevents the cutting edges 
striking the same point twice and produces 
more rapid work. (Fig. 128.) Drill hole 
slightly deeper than the length of the shield 
to be inserted so that the lag screw will

project beyond the inner end and enable turning the 
work up tight to the wall when the screw is turned in. 


Where few holes are to be drilled a hand hammer with a 
rose drill will give good results, but for larger work requir- 
ing numerous holes a great saving in time may be made by 
using a “Rapid Fire”’ drill. This drill works similarly to 
a pneumatic hammer. 


After the hole is drilled accurately the shield can be in- 
serted by hand or lightly driven in by hammer. (F ig. 129.) 
Drive beyond the face of the wall. Then place the plate or 
bracket to be attached, over the shield; then insert lag 
screw by hand as far as can be turned and continue turn- 
ing with hand wrench or socket wrench in a brace until it 
has tightly drawn the work up against the wall. (Fig. 130.) 


Good Practice for Installing—Continued 


If lag screw binds at any point 
due to grit from wall, give it a 
reverse turn and then continue.

AMERICAN PEERLESS 
WALL RADIATORS 


For Roundhouses and Bulkheads 


ANY engineers maintain that railroad roundhouses 
should be equipped with blower systems, but never- 
theless a great deal of Wall Radia- 
tion is used in this class of buildings. 
In many cases both systems are used. 


AMERICAN Peerless Wall Radiators 
are adapted excellently to round- 
house engine pits. They are narrow 
and, when mounted on Arco Adjust- 
able Wall Brackets, do not extend 
out more than 434 inches from the 
wall. They serve particularly well 
when the heating surface in these 
engine pits is recessed. 


Fig. 136. AMERICAN Peer- 
less Wall Radiator recessed 
inside wall of engine pit. 


AMERICAN Peerless Wall Radiator 


“A” sections are only 13,5, inches in height. Therefore a 
run of many of these rons assembled end to end, may 
be set in an engine pit at a pitch that is sufficient to in- 
sure perfect drainage. 


The new Arco Adjustable Wall Bracket is perfectly suited 
for the work that is required of it. The fact that its ad- 
justment may be accomplished after the Wall Radiators 
are set in place is exceedingly important. By reason of 
this feature the contractor using AMERICAN Peerless Wall 
Radiators finds that his labor item is agreeably reduced. 


AMERICAN Peerless Wall Radiators, used in bathrooms, 
halls, kitchens, food-packing plants, butcher shops, res- 
taurants, Turkish baths, laundries, lavatories, hospital 
operating rooms, sick wards, etc., leave a clear space be- 
neath them which can be easily scrubbed or cleaned.

Arco Trapeze and Slip End Supports 


Ree the necessity for a change from the make- 
shift arrangements used for strapping or hanging 
pipe, conduits, radiators, etc., from ceilings, beams or 
girders, we have designed these ARCO Trapeze Supports 
with the view of furnishing a permanent as well as an 
adjustable and neat-appearing hanger. 


Figs. 138, 152 and 153, on pages 26 and 30, 
show the Arco Trapeze Support employed in 
hanging an AMERICAN Peerless Wall Radiator, 
with its supply and return pipes, in addition 
to plumbers’ pipes. 


Any arrangement or combination can be as- 
sembled on the job quickly by using standard 
nipples or cut pipe slipped over rods between 
Supports. The ARCO Slip End Supports, in 
conjunction with the single and double ARco 
Trapeze Supports, permit many additional

AMERICAN PEERLESS 
WALL RADIATORS 


FTEN it is highly desirable to employ AMERICAN Peerless Wall Radi- 

ators as Ceiling Radiators. Nothing detracts so greatly from the 
appearance of an installation as the employment of makeshift, insecure- 
appearing straps, bands, chains and the like, whereas the orderliness and 
neatness of the heating installation receive much favorable comment where 
the hanging of ceiling radiators and piping is simply and sturdily effected 
by use of these substantial and reliable ARCO Trapeze and Slip End Supports. 


Besides, these ARCO Trapeze and Slip End Supports permit easy adjust- 
ment in pitch of piping and radiators or conduits at any time, whether to 
make up for irregularities in setting or in settling of the building. 


The slight difference, if any, in cost is more than offset by the lower labor 
cost in erecting and adjusting these Supports. 


A few examples of arrangements of these Supports are illustrated in 
pages 26, 30 and 45 to 47.

Arco Clearway Forms 


RCO Clearway Forms, as shown on opposite page, 
have been successfully and economically used. When 
placed in a pier or pilaster, a clear pathway is made for 
the piping, thus overcoming the unsightly and expensive 
practice of elbowing around these projections. These forms 
should be delivered to the builder with instructions as to 
their positions. These are made to take up the height of 
two and three flat brick courses. 


ARCO Clearway Forms can also be used on overhead pip- 
ing where it is desired that pipes be out of the way of 
other apparatus. 


Placing these Forms end to end at the center of the wall 
radiator tappings enables units of any length to be made 
—all radiators between piers being connected together on

a straight line. ARCO Clearway Forms are made of cast 
iron, in three sizes, as listed on this page. 


Where there are deeper recesses between piers or pilasters, 
the ARCO Backset Connections, as illustrated on page 35, 
offer a mechanically skillful means of neatly disposing of 
the radiators, causing them to hug the wall closely.

Arco Safety Concrete Insert 


i Bee ARCO Safety Concrete Insert is adaptable to a 

great variety of work where heavy equipment must 
be hung from concrete walls or ceilings. Its large base and 
large surface area insure great holding power. It is easily 
placed and held in the desired position and cannot be 
dislodged by the falling concrete while pouring the wall. 
The expanding shoe is sturdy enough to prevent the bolt 
from pulling out of the Insert. 


Fig. 172, page 37, shows ARCO Safety Concrete Insert 
nailed, in position, to inside of wall form. Ready to pour 
concrete. 


Fig. 173, page 37. Concrete has been poured, form stripped,

Arco Greenhouse Radiator Post Supports 


Ate Greenhouse Radiator Post Supports give to greenhouse men 
a long-sought, permanent means of installing radiator heating sur- 
faces under benches, and insure a construction doing away with the vex- 
atious, costly troubles from sagging, trapped coils and split headers. 


These Supports are made in size to 
cap a 5-inch concrete molded post. 
(See Fig. 201, page 50.) The two ears, 
with their 5£-inch rods, uphold the 
ARCO heavy cast-iron saddles, upon 
which rest the stacks of AMERICAN 
Peerless Wall Radiators. The threaded 
rods permit raising or lowering the 
saddles, to insure correct drainage of 
heating surfaces and piping as long as

Wie than fifty thousand installations of AMERICAN Peerless Wall Radiators have been made in about every 
form or class of structure or place that can be imagined. This large number of shipments precludes the show- 
ing of acomplete list here. In these installations more than thirty million square feet of AMERICAN Peerless Wall 
Radiators are used. A special list of installations in any specified locality will be supplied on application.

AMERICAN PEERLESS 
WALL RADIATORS 


HCHER Working Pressures— AMERICAN Peerless Wall 
Radiators are regularly tested at the factory at from 
100 to 120 pounds cold water pressure, but where higher 
working pressures (steam or water) than 40 pounds are re- 
quired order must specifically so state. In these cases wall 
radiators are furnished only with outside hexagon nipples. 


For Convenience in Handling and Shipping in less than car- 
load lots, unless otherwise ordered, No. 5-A Radiators will 
be assembled in stacks not exceeding six sections; No. 7-A 
Radiators in stacks not exceeding four sections; No. 9-A 
Radiators in stacks not exceeding three sections; and Nos. 
7-B and 9-B Radiators in stacks not exceeding seven sec- 
tions. See page 54 for schedule of shipping Wall Radiators 
in stacks or units, as followed in our factory practice, un- 
less otherwise ordered. 


Directions for Ordering 


When Erecting Large Stacks— When fitter intends to 
erect a stack consisting of more sections than above men- 
tioned, or when the sections or stacks are to be set in 
rows or series (as shown by illustrations on pages 58 to 60), 
we provide a right- and left-hand threaded nipple having 
hexagon nut at center, enabling the fitter easily to connect 
the stacks or rows on the job. 


The 11-inch right- and left-hand threaded internal nip- 
ples have two heavy inside lugs so that an ordinary piece 
of l1-inch round iron, flattened at one end the length of 
nipple, can be inserted to any desired point in the Radia- 
tor, and by applying an ordinary wrench to bar the nipple 
can be screwed or unscrewed and one or more sections may 
be added or taken out. We can furnish these bars (Direct 
Radiator Wrenches) in 4-foot lengths.

60.) The first numeral in each of the following figure 
numbers indicates the size of section, thus: Fig. 511 
means 5-foot sections arranged in the manner as shown 
in sketch above the number; Fig. 711 refers to 7-foot 
sections and to the same assemblage; and Fig. 911 refers 
to 9-foot sections and to the same assemblage. 


Assemblages—Sections are always assembled with bars 
vertical for greatest heating efficiency. The figures shown 
on these pages illustrate the common ways of assembling 
comparatively small units, but AMERICAN Peerless Wall 
Radiators can be assembled in any number of sections, 
either longer or higher than shown in the figures. It is 


Assemblage Figures and Tappings 


our practice, however, when a greater number of sections 
are specified than exactly shown in the figure, always to 
build on to the length, maintaining the height as shown in 
the figure. The safe way in ordering is always to send 
sketch unless you are ordering exactly the number of sec- 
tions as shown in the figure. 


Regular and Special Tappings—The regular tappings of 
AMERICAN Peerless Wall Radiators, as shown on the 
following pages, are indicated by Nos. 2, 3, 4, 5, 6, 7, 8 
and 9. Nos. 20, 30, 40, 50, 60, 70, 80 and 90 indicate special 
tappings which can be furnished if desired and for which 
an extra charge will be made. Tappings are 11% inches, 
supply and return, and bushed as desired. See also

The appointment of a competent engineer to cooperate with the architect during preparation of the building plans and specifications is an act of wisdom on the

well as in operation.
